What Are "Star" Ratings?

a7_3star Reliable and relatively consistent scientific data showing a substantial health benefit.

a7_2star Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

a7_1star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Constipation
5 to 10 grams daily in water, followed by a second glass of water3 stars Psyllium is a mild bulk-forming laxative that’s best suited for long-term use in people with constipation.

3 stars Constipation

5 to 10 grams daily in water, followed by a second glass of water

The laxatives most frequently used world-wide come from plants. Herbal laxatives are either bulk-forming or stimulating.

Bulk-forming laxatives come from plants with a high fiber and mucilage content that expand when they come in contact with water; examples include psyllium, flaxseed, and fenugreek. As the volume in the bowel increases, a reflex muscular contraction occurs, stimulating a bowel movement. These mild laxatives are best suited for long-term use in people with constipation.

Many doctors recommend taking 7.5 grams of psyllium seeds or 5 grams of psyllium husks, mixed with water or juice, one to two times per day. Some doctors use a combination of senna (18%) and psyllium (82%) for the treatment of chronic constipation. This has been shown to work effectively for people in nursing homes with chronic constipation.1


Used for AmountWhy
Diverticular Disease
7 grams daily in water, followed by a second glass of water3 stars A preliminary trial found that psyllium, a good source of fiber, was effective in relieving the symptoms associated with diverticular disease and constipation.

3 stars Diverticular Disease

7 grams daily in water, followed by a second glass of water

A preliminary trial of the herb psyllium supports the use of this type of fiber in relieving the symptoms associated with diverticular disease and constipation.2


Used for AmountWhy
High Cholesterol
5 to 10 grams per day with meals3 stars Psyllium has been shown to be effective at lowering total and LDL (“bad”) cholesterol.

3 stars High Cholesterol

5 to 10 grams per day with meals

Use of psyllium has been extensively studied as a way to reduce cholesterol levels. An analysis of all double-blind trials in 1997 concluded that a daily amount of 10 grams psyllium lowered cholesterol levels by 5% and LDL cholesterol by 9%.3 Since then, a large controlled trial found that use of 5.1 grams of psyllium two times per day significantly reduced serum cholesterol as well as LDL-cholesterol.4 Generally, 5 to 10 grams of psyllium are added to the diet per day to lower cholesterol levels. The combination of psyllium and oat bran may also be effective at lowering LDL cholesterol.5


Used for AmountWhy
Irritable Bowel Syndrome
3.25 grams taken three times per day3 stars Some people with IBS may benefit from bulk-forming laxatives. Psyllium has helped regulate normal bowel activity and improved symptoms in some people with IBS.

3 stars Irritable Bowel Syndrome

3.25 grams taken three times per day

Some people with IBS may benefit from bulk-forming laxatives. Psyllium seeds (3.25 grams taken three times per day) have helped regulate normal bowel activity in some people with IBS.6 Psyllium has improved IBS symptoms in double-blind trials.7 , 8


Used for AmountWhy
Type 2 Diabetes
5.1 grams daily with meals3 stars Supplementing with psyllium has been shown to be a safe and well-tolerated way to improve control of blood glucose and cholesterol.

3 stars Type 2 Diabetes

5.1 grams daily with meals

Supplementing with psyllium has been shown to be a safe and well-tolerated way to improve control of blood glucose and cholesterol. In a double-blind trial, men with type 2 diabetes who took 5.1 grams of psyllium per day for eight weeks lowered their blood glucose levels by 11 to 19.2%, their total cholesterol by 8.9%, and their LDL (bad) cholesterol by 13%, compared with a placebo.9

Used for AmountWhy
Diarrhea
9 to 30 grams daily2 stars Psyllium seed (an excellent source of fiber) makes stool more solid and can help resolve diarrhea symptoms.

2 stars Diarrhea

9 to 30 grams daily

While fiber from dietary or herbal sources is often useful for constipation, it may also play a role in alleviating diarrhea. For example, 9–30 grams per day of psyllium seed (an excellent source of fiber) makes stool more solid and can help resolve symptoms of non-infectious diarrhea.10 Alginic acid, one of the major constituents in bladderwrack(Fucus vesiculosus), is a type of dietary fiber and as a result may potentially help relieve diarrhea. However, human studies have not been done on how effective bladderwrack is for this condition.


Used for AmountWhy
Hemorrhoids
7 grams three times daily in water, followed by a second glass of water2 stars Taking psyllium, an herb high in fiber, may help relieve constipation.

2 stars Hemorrhoids

7 grams three times daily in water, followed by a second glass of water

Constipation is believed to worsen hemorrhoid symptoms, and thus, bulk-forming fibers are often recommended for those with hemorrhoids. A double-blind trial reported that 7 grams of psyllium, an herb high in fiber, taken three times daily reduced the pain and bleeding associated with hemorrhoids.11 Some healthcare professionals recommend taking two tablespoons of psyllium seeds or 1 teaspoon of psyllium husks two or three times per day mixed with water or juice. It is important to maintain adequate fluid intake while using psyllium.


Used for AmountWhy
High Triglycerides
15 grams daily2 stars Psyllium seeds and husks have shown a modest ability to lower blood triglyceride levels in some clinical trials.

2 stars High Triglycerides

15 grams daily

Psyllium seeds and husks have shown a modest ability to lower blood triglyceride levels in some,12, 13 but not all,14 clinical trials. Further research is needed to assess the effect of psyllium on triglyceride levels more closely, as much of the study so far has focused on lowering cholesterol levels.


Used for AmountWhy
Ulcerative Colitis
Refer to label instructions 2 stars Taking psyllium may help people with ulcerative colitis maintain remission.
Parkinson’s Disease and Constipation
3 to 5 grams taken at night with a one to two glasses of fluid 1 star Preliminary research has shown that psyllium seed husks improve constipation and bowel function in people with Parkinson’s disease and constipation.

1 star Parkinson’s Disease and Constipation

3 to 5 grams taken at night with a one to two glasses of fluid

Doctors recommend that people with Parkinson’s disease supplement with fiber and maintain adequate fluid intake to reduce constipation associated with this disease.15 Preliminary research has shown that psyllium seed husks improve constipation and bowel function in people with Parkinson’s disease and constipation.16 A typical recommendation for psyllium seed husks is 3 to 5 grams taken at night with a one to two glasses of fluid.

Traditional Use (May Not Be Supported by Scientific Studies)

In addition to its traditional and current use for constipation, psyllium was also used topically by herbalists to treat skin irritations, including poison ivy reactions and insect bites and stings. It has also been used in traditional herbal systems of China and India to treat diarrhea, hemorrhoids, bladder problems, and high blood pressure.

About this treatment

Flea Seed, Ispaghula, Psyllium Husk, Spogel
Botanical names:
Plantago ispaghula, Plantago ovata

How It Works

Psyllium is a bulk-forming laxative and is high in both fiber and mucilage. Psyllium seeds contain 10–30% mucilage. The laxative properties of psyllium are due to the swelling of the husk when it comes in contact with water. This forms a gelatinous mass that keeps feces hydrated and soft, provided it is taken with sufficient water. The resulting bulk stimulates a reflex contraction of the walls of the bowel, followed by emptying.

Psyllium is a common ingredient in over-the-counter bulk laxative products. One preliminary trial found that psyllium seeds relieved constipation when it was due to lifestyle factors (e.g., inadequate fiber, sedentary lifestyle), but not when an actual disease was the cause. Numerous double-blind trials have found that supplementation with psyllium can lower total cholesterol and LDL (“bad”) cholesterol. However, levels of HDL (“good”) cholesterol are not affected by psyllium supplementation. The cholesterol-lowering effect of psyllium has been reported in children, as well as in adults. Psyllium supplementation has also improved blood sugar levels in some people with diabetes. The soluble fiber component of psyllium is believed to account for this effect.

In a double-blind trial, people with ulcerative colitis had a reduction in symptoms such as bleeding and remained in remission longer when they took 20 grams of ground psyllium seeds twice daily with water compared to the use of the medication mesalamine alone. Also, the combination of the two was slightly more effective than either alone.

How to Use It

The suggested intake of psyllium husks to treat constipation is 1 teaspoon (approximately 5 grams) three times per day. Alternatively, some references suggest taking 2–6 teaspoons (10–30 grams) of the whole seeds per day—typically taken in three even amounts throughout the day. This is stirred into a large glass of water or juice and drunk immediately before it thickens. It is best to follow label instructions on over-the-counter psyllium products for constipation. It is important to maintain a high water intake when using psyllium.
